1. Application Information: The pin STROBE is usually connected directly to the camera processor.

2. When SCL and SDA exchanged, the AS3630 uses a different I²C address and the functionality of SCL/SDA is also exchanged - see “I²C Address

Selection” on page 43.

3. Only input: The AS3630 does not perform clock stretching.
